Author Block Masks
Customize block appearance, user interface, and block diagram
Simulink® enables you to create block masks. A mask is a custom user interface for a block.
By masking a block you encapsulate the block diagram to have its own parameter dialog box with its own block description, parameter prompts, and help texts.
You can mask an independent custom block that you can reuse as unique blocks like those defined in Simulink.
To know about creating a block mask, see Create a Simple Mask.

Introduction to Masking
- Masking Fundamentals
Learn the basics about masking and when to mask blocks. - Create a Simple Mask
You can mask a block interactively by using the Mask Editor or mask it programmatically. - Manage Existing Masks
View or edit an existing block mask.
Mask Editor User Interface
- Mask Editor Overview
Create and customize masks using the Mask Editor interface. - Design a Mask Dialog Box
Try this example to create a mask dialog box and understand the use of some Mask Editor features. - Handling Large Number of Mask Parameters
Add large number of mask parameters in a Table programmatically. - Customize Tables for Masked Blocks
Add custom tables to mask dialog box. - Control Custom Table Programmatically
Use a programmatic interface to control custom tables. - Control Masks Programmatically
Simulink® defines a set of APIs that help in setting and editing masks.
Masking Features
- Validating Mask Parameters Using Constraints
Add validation to mask parameters using constraints. - Custom Constraint for Mask Parameter
A mask can contain parameters that accept user input values. - Share Parameter Constraints Across Multiple Block Masks
This example shows how to create a parameter constraint and share it across masks of different blocks in the same model or different models. - Validate Input and Output Port Signals Using Port Constraints
You can validate compile-time signal attributes on the input and output ports of a masked block by using port constraints. - Validate Port Signals Among Ports of the Same Masked Block
This example shows how to create cross port constraints to validate compile-time signal attributes among ports of the same masked block. - Share Port Constraints Across Multiple Masked Blocks
This example shows how to create a port constraint and share it across masks of different blocks in the same model or different models. - Author Parameter and Port Constraints Using Standalone Constraint Manager
When creating masks for Simulink blocks, there are specific constraints and considerations related to parameters and ports. - Promote Block Parameters on a Mask
Blocks and subsystems can have multiple parameters associated with them. - Specify Data Types for an Edit Parameter Using Data Type Parameter
You can specify the acceptable data types for a mask edit parameter with a data type parameter. - Pass Values to Blocks Under the Mask
Specify input values using the mask dialog box. - Mask Linked Blocks
Add custom interface to linked blocks. - Approaches to Control Active Variant Choice of a Variant Block Using Mask or Model Workspace
This example shows different approaches to control the active choice of inline variant and Variant Subsystem blocks from a mask or a model workspace. - Define Measurement Units for Masked Blocks
Set measurement units for output and input ports of a masked block. - Add Images in Masks
Add images as mask icons and save them in the SLX file. - Create Hierarchical List in Mask Dialog
Create a hierarchical list of data on a mask. - Tune Mask Enumeration Parameters - Popup and Radio Button
Reference external enumeration file to assign numerical values to popup parameter. - Visualize and Plot N-Dimensional Data Using Mask Lookup Table Control
Use a lookup table to evaluate a sampled representation of a function using simple lookup operations. - Preserve Tunability of Parameters That Are Modified or Created in Mask Initialization
A desirable feature of code generated from a model is the ability to tune variables to different values. - Reuse Mask Parameters and Dialog Controls Across Multiple Masked Blocks
Use the Mask Part Reference container of the Mask Editor to create and save the parameters and dialog controls in an XML file.
Graphical Icon Editor
